There’s an organism that changed the world. It caused the first mass extinction in Earth’s history … and also paved the way for complex life. How? Anusuya Willis explains how cyanobacteria, simple organisms that don’t even have nuclei or any other organelles, wrote a pivotal chapter in the story of life on Earth.

Progress in Parapsychology with Stanley Krippner

source: New Thinking Allowed    2016年6月16日
Stanley Krippner, PhD, professor of psychology at Saybrook University, is a Fellow in five APA divisions, and past-president of two divisions (30 and 32). Formerly, he was director of the Maimonides Medical Center Dream Research Laboratory, in Brooklyn NY. He is co-author of Dream Telepathy, Extraordinary Dreams and How to Work with Them, The Mythic Path, and Haunted by Combat: Understanding PTSD in War Veterans, and co-editor of Debating Psychic Experience: Human Potential or Human Illusion, Healing Tales, Healing Stories, Varieties of Anomalous Experience: Examining the Scientific Evidence, Advances in Parapsychological Research and many other books. He is a Fellow of the Society for the Scientific Study of Religion, and has published cross-cultural studies on spiritual content in dreams.
Here he reviews his half-century of experience as a parapsychologist, pointing out that the American Psychological Association has always been open to his symposium proposals and has published two editions of Varieties of Anomalous Experience. Parapsychology still has hurdles to overcome with regard to replication. However, the same problem exists in all other behavioral and social sciences. Over the decades, he has become more comfortable with the data supporting the hypothesis that human consciousness can survive the death of the physical body.

New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities.

Kepler's Trial: An Opera

source: Cambridge University   2016年7月6日
Johannes Kepler - 1571-1630, is one of history’s most admired astronomers. He defended Copernicus's sun-centred universe and defined the three laws of planetary motion. Less well known is that in 1615, when Kepler was at the height of his career, his widowed mother Katharina was accused of witchcraft. The proceedings led to a criminal trial, with Kepler conducting his elderly mother's defence. The opera, Kepler's Trial, responds to Paul Hindemith's Harmony of the World and other accounts which present Katharina as deranged and witch-like. Based on fresh historical research, by Professor Ulinka Rublack in her book "The Astronomer & the Witch", the new work counters the endemic misogyny against old women which prevailed in the ‘witch-craze’ and continues to be a cultural force. Instead, the book, opera and film explore with sensitivity, empathy and nuance what it meant for Johannes and Katharina to face accusations of witchcraft. The performance is the outcome of a highly unusual creative process, in which a group of scholars met regularly to explore the story. Tim Watts’ opera seeks to illuminate the story through the combination of allusions to the music of the early 17th century with video sequences by Aura Satz that amplify its themes of darkness and light, sight and illusion. At its centre is the depiction of the ageing woman.
Premieres on the 28 October 2016 at St John¹s College, Cambridge.

J. Bradford Hipps: "The Adventurist" | Talks at Google

J. Bradford Hipps turned to fiction after a 10-year career as a programmer. His first novel, “The Adventurist,” aims for a workplace and people invested with the joys and sadnesses of lived experience. Kirkus called it “just about perfect: incisive, eloquent, philosophical, and witty by turns. .. Hipps finds illumination about the meaning of life everywhere he looks.” Hipps also contributed an op-ed to the New York Times Sunday Review that explores a forgotten link between software and creativity.
